12 Install WashBox System The WashBox System is a secondary belt cleaning device and as such should be located on the return side of the belt after the belt leaves contact with the head pulley. Preferably it should be located before and after a set of return idlers to help steady the belt, in order to dampen system vibration. This will ensure smooth and direct belt contact on the Razor-Back Blade Tips. Direction of belt travel shown below, See Figure 8. BELT Figure 8. Belt Travel Through WashBox The Hangers (17) of the WashBox mount to the frame / structure of the conveyor system. The Hangers have multiple height adjustment holes. The top inside edge of the WashBox should be 0 1 from bottom of the belt. See Figure 9. In most applications it will be necessary to remove the Hold Down Roller for installation of the WashBox. Once the WashBox has been installed in the correct location, the Hold Down Roller can be reinstalled. 0-1/2 Figure 9. WashBox Install Height ASGCO Mfg., Inc WashBox Secondary

13 INTERAL CLEANER ADJUSTMENTS Figure 10. Razor-Back with Spray Bar Adjustment Razor-Back with Spray Bar: Loosen Hex Head Bolt (50) on both tensioners, this will allow for height adjustment of Razor-Back. Adjust height by tightening the Height Adjustment Bolt (52). It may be necessary to move the Height Adjustment Angle (48). Once belt contact has been made, turn the Adjustment Bolt (52) until the blade tip has moved up a maximum of 1/8. Make sure Spray Tube is angled 5-10 degrees into the belt travel. Tighten the tube clamp lock bolts (50, 51). Now test run the conveyor. If chatter occurs, loosen the tube clamp bolts and rotate the blade tip about 5 degrees in the direction of the belt travel (Razorback only). If cleaning performance is unsatisfactory, slightly increase the force against the belt and test it again. If the cleaner has about 1/8 or more of material to remove, a primary cleaner may be needed. Hold Down Roll: Lower or raise the Hold Down Roll so as there is 0 ½ clearance between the bottom of the roll and the top of the conveyor belt. Adjustment of the Razor-Back will take up the gap. Rubber Wipe: Raise the Rubber Wipe by loosening the 4-Arm Knobs (23) and raising the Wipe Holder (13). Then tighten the 4-Arm Knobs to lock the Rubber Wipe in place.

14 MAINTENANCE After one day of operation: Inspect the cleaner for proper belt cleaning and operation. Weekly: Frequent inspection is the key to proper belt cleaning and easy secondary servicing. Weekly inspections are recommended, but actual service frequency may vary widely depending on various plant operating conditions. Wash the entire cleaner regularly to prevent excessive build up. If material tends to accumulate on the secondary assembly then possible scraper relocation may be in order. Carefully inspect the wear tips of the cleaner blades. Make sure blades are not chipped or worn out. Inspect the belt surfaces and edges for cracks, splits, tears, holes or any other worn or damaged condition occurring on the surfaces or edges of the belt itself. If belt is worn or damaged, make necessary repairs. ASGCO Mfg., Inc WashBox Secondary

15 TROUBLE SHOOTING PROBLEM Excess vibration of scraper. SOLUTION Make certain all bolts are tight. If belt is non-reversing, rotate the blade 5 degrees in the direction of belt movement. Check for proper Scraper contact. Put additional force on cleaner. Excess Carryback Excess belt movement, cupping. Unable to tension scraper properly, belt moves away from blades. Frozen material on scraper. Poor Pressure from Spray Nozzles Check for wear on cleaning tips. Check thickness of carryback. If the cleaner must remove more than 1/8 inch of material, then an additional cleaner maybe needed. Install a hold down roller to stabilize the belt surface. Install a hold down roller to reduce sag of the belt when tensioning. Place heaters near scraper to melt frozen material. (Use Caution not to burn belt or cleaner) Check to see if Nozzles are plugged. Check to see if Nozzle filters need to be replaced. ASGCO Mfg., Inc WashBox Secondary
